Abstract
Boutique professional service firms (PSFs) face predictable growth “chasms” at critical revenue thresholds where previously successful practices become constraints on further development. Drawing on comparative case studies of four consultancies and integrating practitioner insights with academic theory, this paper identifies Dynamic Coherence - the organisational meta-capability to orchestrate aligned evolution across strategy, structure, systems, and culture - as the critical differentiator enabling successful transitions through growth inflection points. We delineate four key thresholds faced by boutique PSFs: the founder’s limit (~£2m), the systems barrier (~£6-10m), the platform challenge (~£10-20m), and the market leadership transition (~£20m+). Unlike existing growth models that primarily identify what changes are needed at each stage, our framework explains how firms successfully implement these transformations whilst maintaining organisational identity and coherence. We demonstrate that dynamic coherence operates through three mechanisms: multi-dimensional coordination of change initiatives, temporal alignment of transformation pace, and preservation of core identity through evolution.
